1. Cannot contact ACT Pro and ask them to build an integration (since the RingCentral Platform is open and free developer accounts are available). 2. Build one for your own needs as a Private application. 3. Build one to be published in the RingCentral App Gallery for all RingCentral customers who use ACT Pro.
Do any of those appeal to you?
If they do, you can visit (or share with others) the URI to the RingCentral Developer Portal where anyone can signup for a free developer account and start working with our APIs, SDKs, and developer tools right now!
